Valgrind for Kontact
[daipengg@gurka ~]$ valgrind kontact
==46753==
==46753== Valgrind's memory management: out of memory:
==46753==newSuperblock's request for 4194304 bytes failed.
==46753==69898240 bytes have already been allocated.
==46753== Valgrind cannot continue. Sorry.
==46753==
==46753== There are several possible reasons for this.
==46753== - You have some kind of memory limit in place. Look at the
==46753== output of 'ulimit -a'. Is there a limit on the size of
==46753== virtual memory or address space?
==46753== - You have run out of swap space.
==46753== - Valgrind has a bug. If you think this is the case or you are
==46753== not sure, please let us know and we'll try to fix it.
==46753== Please note that programs can take substantially more memory than
==46753== normal when running under Valgrind tools, eg. up to twice or
==46753== more, depending on the tool. On a 64-bit machine, Valgrind
==46753== should be able to make use of up 32GB memory. On a 32-bit
==46753== machine, Valgrind should be able to use all the memory available
==46753== to a single process, up to 4GB if that's how you have your
==46753== kernel configured. Most 32-bit Linux setups allow a maximum of
==46753== 3GB per process.
==46753==
==46753== Whatever the reason, Valgrind cannot continue. Sorry.
